碩士 === 元智大學 === 化學工程與材料科學學系 === 104 === In the study was prepared composite film by sol-gel process, by methyltriethoxysilane (MTES) and adding different ratios of octyltriethoxysilane (OTES) as a precursor reacts in acidic and alkaline two environments to form different gel structures respectively. Followed by acid catalyzed gel coated on a glass substrate as first layer, and base-catalyzed gel as second layer to accomplish the double-Layered anti-refractive thin film. When MTES and OTES ratio for acid catalyst layer was 1:0.16 and MTES and OTES ratio for base catalyst layer was 1:0.12, the water contact angle reached 109.1° and the average transmittanceat was 99% at a wavelength of 400 ~ 800nm. Therefore, it can be widely used to optical device.
